Shingles Shot

Patient: My husband has never had chicken pox. His latest blood test confirmed this. I would like to get a Shingles shot, but am concerned that if I do, this might expose him to Chickenpox.COULD THIS HAPPEN? He and I are concerned about this; yet, I would like to protect myself from Shingles. If I would be contagious, how long would the contagion period last after my shot? I will appreciate your help.
